Perl::Critic::Policy::RegularExpressions::RequireLineBoundaryMatching
Folks coming from a sed or awk background tend to assume that
'$' and '^' match the beginning and and of the line, rather than
then beginning and ed of the string. Adding the '/m' flag to your
regex makes it behave as most people expect it should.
my $match = m{ ^ $pattern $ }x; #not ok
my $match = m{ ^ $pattern $ }xm; #ok
For common regular expressions like e-mail addresses, phone numbers, dates, etc., have a look at the the Regex::Common manpage module. Also, be cautions about slapping modifier flags onto existing regular expressions, as they can drastically alter their meaning. See http://www.perlmonks.org/ for an interesting discussion on the effects of blindly modifying regular expression flags.
